The flow meter accepts any 4-20 mA water depth measurement input and the meter’s powerful microprocessor instantly calculates and displays water flow and totalizer values in user selectable units using one of several calculation modes. The monitor has an 8-button keypad that easily guides you through the versatile setup menus.
The Open Channel Flow Monitors display water flow with up to 7 digits allowing for very large flows to be displayed. The totalizer records up to 9 digits of flow volume in non-volatile memory, and is password protected from reset.
The water flow monitors have four independent relay outputs for triggering external devices like water samplers and monitoring devices. The monitor's relays can be separately programmed to trigger based on volume per pulse, and threshold settings can be used to limit triggering to flows above preset levels. There is also an accurate and scalable 4-20mA output provided for monitoring the flow using data loggers and PLC devices. Both USB and serial internal data loggers are available as factory options for the monitors to allow the historical flow data to be recorded, as well as the exact time of each relay trigger event.
